Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456232, here are decompositions:

13 + 31456219 = 31456232
109 + 31456123 = 31456232
139 + 31456093 = 31456232
211 + 31456021 = 31456232
229 + 31456003 = 31456232
271 + 31455961 = 31456232
331 + 31455901 = 31456232
373 + 31455859 = 31456232

Showing the first eight; more decompositions exist.
